End Preamble Start Supplemental Information


As part of the NIST WMD mandate to “fix the standard of weights and measures” its staff and the USNWG will meet for the first in-person (and via audio conference) meeting to promote the development of legal metrology standards to facilitate the United States transition to a hydrogen economy. USNWG participants are technical experts working on existing related international and national standards activities, motor-fuel dispenser and component manufacturers and associated service industry, suppliers of motor-fuel products such as hydrogen, service station installers and operators, alternative fuel vehicle manufacturers, or regulatory officials enforcing legal controls over commercial devices.

Establishment of these standards will ensure the selection and use of suitable, approved, and properly maintained equipment that provides accurate hydrogen measurement and sufficient valid transaction information to the buyer and seller. Historically, these standards are adopted by the states as the basis of uniform requirements used to regulate weighing and measuring devices and commodities sold on the basis of weight, measure, or count. The goal of NIST and the USNWG is to establish commercial hydrogen measurement standards that encompass: (1) Device and related equipment codes, (2) method of sale requirements, (3) labeling requirements, (4) quality standards, (5) sampling procedures, (6) inspection procedures, (7) test equipment, and (8) safety practices. These standards and related documents will be the basis for day-to-day commercial operations, training weights and measures regulatory officials and service companies, and educating consumers about hydrogen measurement.
